XWD型臥式靜電除塵器是眾多除塵器當中的一種，臥式靜電除塵器是以靜電凈化法來收捕廢氣中的粉塵的設備，其主要是讓含塵氣體進人氣刺叭時，含塵氣體受到氣流分布板以及折流板的調整后，使氣流能較均勻地進人電場。

臥(wo)式靜電(dian)(dian)(dian)(dian)(dian)除塵(chen)器是以靜電(dian)(dian)(dian)(dian)(dian)凈化(hua)(hua)法來(lai)收捕廢氣(qi)(qi)(qi)中(zhong)的(de)(de)(de)(de)粉(fen)塵(chen)，它的(de)(de)(de)(de)凈化(hua)(hua)工作(zuo)(zuo)上要(yao)是依靠電(dian)(dian)(dian)(dian)(dian)暈極和(he)沉淀兩個系統來(lai)完(wan)成的(de)(de)(de)(de)，當含塵(chen)氣(qi)(qi)(qi)體(ti)進(jin)人(ren)(ren)氣(qi)(qi)(qi)刺叭時，含塵(chen)氣(qi)(qi)(qi)體(ti)受到(dao)氣(qi)(qi)(qi)流(liu)分布(bu)板以及(ji)折流(liu)板的(de)(de)(de)(de)調(diao)整后(hou)，使(shi)氣(qi)(qi)(qi)流(liu)能(neng)較均勻地進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場。在橫斷面擴(kuo)大(da)的(de)(de)(de)(de)作(zuo)(zuo)用(yong)下，氣(qi)(qi)(qi)流(liu)速(su)度迅速(su)降低，其中(zhong)有些較重(zhong)的(de)(de)(de)(de)塵(chen)粒(li)便失去速(su)度而沉降下來(lai)。進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)含塵(chen)氣(qi)(qi)(qi)體(ti)由于(yu)電(dian)(dian)(dian)(dian)(dian)暈極通(tong)人(ren)(ren)高壓(ya)直流(liu)電(dian)(dian)(dian)(dian)(dian)，則在電(dian)(dian)(dian)(dian)(dian)暈極附近產生(sheng)電(dian)(dian)(dian)(dian)(dian)暈現象，使(shi)氣(qi)(qi)(qi)體(ti)電(dian)(dian)(dian)(dian)(dian)離(li)，電(dian)(dian)(dian)(dian)(dian)離(li)后(hou)的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)中(zhong)存在大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和(he)離(li)子(zi)(zi)(zi)，這些電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)和(he)離(li)子(zi)(zi)(zi)與(yu)進(jin)人(ren)(ren)電(dian)(dian)(dian)(dian)(dian)場的(de)(de)(de)(de)粉(fen)塵(chen)結合(he)起來(lai)，使(shi)塵(chen)粒(li)帶(dai)電(dian)(dian)(dian)(dian)(dian)，帶(dai)電(dian)(dian)(dian)(dian)(dian)塵(chen)粒(li)在電(dian)(dian)(dian)(dian)(dian)場力(li)的(de)(de)(de)(de)作(zuo)(zuo)用(yong)下趨向本設(she)備(bei)陽(yang)極(正(zheng)極、本設(she)備(bei)采用(yong)負(fu)高壓(ya)制)和(he)陰極(負(fu)極) ， 釋放(fang)出電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)分別沉積在相(xiang)應的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極上，通(tong)過設(she)備(bei)陰陽(yang)極振打(da)(da)系統的(de)(de)(de)(de)振打(da)(da)，使(shi)沉積在陰陽(yang)電(dian)(dian)(dian)(dian)(dian)極上的(de)(de)(de)(de)粉(fen)塵(chen)振落，進(jin)人(ren)(ren)集灰(hui)斗 通(tong)過排灰(hui)裝置放(fang)出，回(hui)收有物料，被)凈化(hua)(hua)的(de)(de)(de)(de)氣(qi)(qi)(qi)體(ti)排入大(da)氣(qi)(qi)(qi)。

工作(zuo)原理

靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)工作原理是利用(yong)高壓(ya)電(dian)(dian)(dian)(dian)(dian)場(chang)使煙氣(qi)發(fa)生電(dian)(dian)(dian)(dian)(dian)離，氣(qi)流中的(de)(de)(de)粉塵(chen)(chen)(chen)(chen)(chen)荷電(dian)(dian)(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)(dian)(dian)場(chang)作用(yong)下(xia)與氣(qi)流分離。負極由(you)(you)不同斷面形(xing)狀的(de)(de)(de)金屬導線制(zhi)(zhi)成(cheng)(cheng)，叫(jiao)放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)極。正極由(you)(you)不同幾何形(xing)狀的(de)(de)(de)金屬板制(zhi)(zhi)成(cheng)(cheng)，叫(jiao)集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極。靜電(dian)(dian)(dian)(dian)(dian)除(chu)塵(chen)(chen)(chen)(chen)(chen)器(qi)的(de)(de)(de)性(xing)能受(shou)粉塵(chen)(chen)(chen)(chen)(chen)性(xing)質、設備(bei)構造和煙氣(qi)流速等三(san)個因素(su)的(de)(de)(de)影響。粉塵(chen)(chen)(chen)(chen)(chen)的(de)(de)(de)比電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)是評價(jia)導電(dian)(dian)(dian)(dian)(dian)性(xing)的(de)(de)(de)指標，它對除(chu)塵(chen)(chen)(chen)(chen)(chen)效率有直接(jie)的(de)(de)(de)影響。比電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過(guo)低，塵(chen)(chen)(chen)(chen)(chen)粒難以保持(chi)在(zai)集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極上，致使其重返氣(qi)流。比電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)過(guo)高，到達集(ji)塵(chen)(chen)(chen)(chen)(chen)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)(de)塵(chen)(chen)(chen)(chen)(chen)粒電(dian)(dian)(dian)(dian)(dian)荷不易(yi)放(fang)出，在(zai)塵(chen)(chen)(chen)(chen)(chen)層之間形(xing)成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)壓(ya)梯度會產生局(ju)部(bu)擊穿(chuan)和放(fang)電(dian)(dian)(dian)(dian)(dian)現象。這些(xie)情況都(dou)會造成(cheng)(cheng)除(chu)塵(chen)(chen)(chen)(chen)(chen)效率下(xia)降。

電(dian)(dian)(dian)除塵器的(de)基本原(yuan)理(li)是利用電(dian)(dian)(dian)力捕集(ji)煙氣中的(de)粉(fen)塵，主要包括以下四個相互有(you)關的(de)物理(li)過程: (1) 氣體的(de)電(dian)(dian)(dian)離。(2) 粉(fen)塵的(de)荷(he)(he)電(dian)(dian)(dian)。(3) 荷(he)(he)電(dian)(dian)(dian)粉(fen)塵向(xiang)電(dian)(dian)(dian)極(ji)移動。(4) 荷(he)(he)電(dian)(dian)(dian)粉(fen)塵的(de)捕集(ji)。
